On the main Singer sewing machine factories | #LRCrafts - DIY Passion: if you can think it, you can make it
I am constantly working to improve and expand the Singer serial number database, as I collect new information and examin existing data.
I began with research into factories such as Monza and Bonnières, whose production figures were largely lost over time. In cases like these, when original records are not preserved, serial numbers alone are often not enough to fully understand when a Singer machine was produced or even which model it is. My goal is instead that you can search for a serial number and get all the information you need about your machine.
At some point, I also started collecting data about decals and added a dedicated page for this research. From there, I asked myself: what other data do I already have that could help narrow down the production period of a machine? There was a lot to be done, so I decided to start by analysing the data already present in the database. So I began digging more deeply into all known Singer factories, with particular attention to those that were assigned serial number prefixes.
On this page, I bring together the data currently available for each factory: known serial prefix allocations, location codes used in model numbers, operating dates, and short historical notes where sources allow. The information is based primarily on the extensive work done by SingerSewingInfo.co.uk and ISMACS, along with other reliable sources.
For some factories listed here, you’ll find a section called “Verified machines”. Our database records a number of vintage Singer sewing machines whose serial numbers have been confirmed on actual machines, either personally seen by me or reported by expert collectors. Gathering those real-life data allows me to link together all the available information about those machines, to connect factories with the models produced there with the decals in use.
The long-term goal is to use all the data I collect not just as reference material, but as an active part of the dating process, making it possible to narrow down the production period of a machine even when a precise serial-number date is not available.
Overview of Singer factories and their history
Singer’s manufacturing history began on a small scale in the early 1850s, with sewing machines produced in a modest machine shop in Boston, Massachusetts. As demand increased, production soon shifted to New York, where Singer operated at first a small workshop, where the company produced machines in limited quantities, reliying on handcrafted methods, using manufacturing processes that were still far from standardized. Isaac M. Singer then moved to bigger facilities as his company expanded, gradually leaving handcrafted processes to adopt modern industrial manufacturing systems. This shift allowed for rapid increases in output and consistent machine design, laying the foundation for Singer’s global expansion.
One of the earliest steps in this transformation was the establishment of Singer’s first Scottish factory in Glasgow in 1867. Initially modest in scale, this facility was quickly outgrown. After a temporary move to an intermediate site, Singer constructed a large, purpose-built factory at Kilbowie, Clydebank, on a 46-acre site along the River Clyde. Kilbowie became one of the two principal international manufacturing centres of the Singer company and remained in operation until the late 20th century, representing nearly a century of continuous production.
The second major international factory was established in Elizabethport, New Jersey, in 1872. Built on a 32-acre site, it replaced Singer’s earlier New York workshops and consolidated American production in a single, highly modern facility. Elizabethport became the primary manufacturing hub for the United States and an essential supplier of parts, machinery and technical expertise for other Singer factories worldwide. Like Kilbowie, it remained operational into the 1980s.
Together, the Elizabethport and Kilbowie factories formed the backbone of Singer’s manufacturing system. They shared design and development work, produced large volumes of complete machines, and supplied components to many smaller factories. Around these two centres, Singer developed a growing network of regional factories intended to serve local markets, reduce transportation costs, and manage import duties and trade restrictions.
At the turn of the 20th century, Singer expanded further into Europe and beyond. Major new factories opened in Podolsk (Russia) and Wittenberge (Prussia, later Germany). Additional factories were established in France (Bonnières), Germany (Karlsruhe), Italy (Monza), Canada (Montreal and later Saint-Jean-sur-Richelieu), and elsewhere. These facilities varied in size and capability. Some produced complete machines from raw castings, while others primarily assembled machines using parts supplied by the larger factories.
In North America, the Bridgeport, Connecticut factory was an important center for industrial machines and specialist components. Cabinet production was concentrated at large facilities such as South Bend, Indiana, supported by timber-processing operations like the Thurso sawmill in Canada. In the mid-20th century, the Anderson, South Carolina factory focused on advanced domestic machines, assembling models such as the slant-needle series using parts produced elsewhere.
As Singer’s global presence continued to grow, factories were established in South America, Australia and Asia, including Campinas (Brazil), Penrith (Australia), Utsunomiya (Japan), and later facilities in Taiwan.
Not all Singer factories operated in the same way: some functioned primarily as assembly plants, others as fully integrated manufacturing sites, and some changed roles over time. Despite these differences, Singer’s factories formed an interconnected global system. Serial numbers, prefix letters and location codes provide crucial clues to how this system functioned and how individual machines fit within it.
Location codes vs. serial number prefixes
Factories are related to two sets of letters, and it’s important to know that they serve two very different purposes: location codes and serial number prefixes.
Location codes are single letters you find in the model number of a Singer machine. The complete model number starts with a digit representing the class, which indicates the basic design of the machine (the main type, we could say). The class number is usually followed by the location code, identifying the factory where that particular model was intended to be produced. Most major factories that produced complete machines were given a unique location code, while smaller factories often lacked one, as they primarily assembled parts produced in larger facilities.
After the location code letter, a full model number may include another number (usually one to three digits), known as the variant or sub-version. This indicates optional features of that particular class. Machines of the same variant are identical, no matter in which factory they were made: a 15K88 is the same machine as a 15M88, though the first was produced in Kilbowie and the second in Monza.
A special case is the Elizabethport factory, which was assigned a dash “-” as a location code. This can be misleading, because the same dash is also used in model numbers for machines made in factories without an assigned location code, or simply to indicate a generic model regardless of production site.
You may also notice a particular set of letters that looks like a factory identifier but actually means something else: “SV”. These letters stand for “special variety” or “special variant”, and appear after the proper location code, as in models 16KSV3 or 45SV58. Singer produced an enormous number of highly specialized machines for specific industrial tasks. If you browse manuals for industrial models, you’ll find machines designed for very narrow uses: for example, the 32-64 for serging and attaching binding to carpets, the 46K27 for sewing gloves and furs, or the 157-4 for medium burlap bags… Beyond standardized models, Singer also accepted custom requests from specialized industries, producing special variants when required.
Serial number prefixes, on the other hand, are one or two letters placed before the serial number itself. They identify the factory to which a block of serial numbers was allocated. In the 19th century, serial numbers consisted only of digits, and machines were produced primarily at Kilbowie or Elizabethport. Numbers were issued sequentially and never reused between factories, ensuring that every machine had a unique identifier.
As production expanded and new factories opened worldwide, this system became increasingly difficult to manage. With the turn of the 20th century, as production grew and new factories opened worldwide, Singer therefore began adding letter prefixes to serial numbers: this allowed each factory to work within its own clearly separated number ranges and greatly reducing the risk of overlap.
List of Singer factories with their location codes and serial number prefixes
Below is a table listing the main Singer factories, together with their location codes and/or serial number prefixes. Large facilities such as the two main international factories at Kilbowie and Elizabethport were assigned several serial number prefixes, while smaller factories generally had fewer.
It’s important to note that serial prefixes were allocated to a factory, but that does not mean all of them were necessarily used. In some cases, a factory closed before it had the chance to produce machines using every prefix assigned to it.
The table also includes the opening and (when available) closing year of each factory. Some of these facilities are no longer in operation, while others of more recent opening are still active today.

Singer factories around the world
The following list presents the main Singer factories, arranged in chronological order by year of opening. Each one includes its location code and serial number prefixes assigned to it where known, and a brief historical note summarising its role within Singer’s manufacturing system. Where additional research is available, links are provided for further reading.
For clarity, the factories are grouped into three broad categories. Early factories include Singer’s first production sites and transitional workshops from the company’s formative years. Main international factories cover the large, fully integrated plants that formed the core of Singer’s global manufacturing operations: Elizabethport and Kilbowie. Other regional factories include later or smaller facilities established to serve local markets, assemble machines from imported parts, or support specific types of production.
A note on verified machines
For some factories listed here, you’ll find a section called “Verified machines”. Those are Singer sewing machines whose serial numbers have been confirmed on actual machines, either personally seen by me or reported by expert collectors. The final goal is to record all available details for each verified machine and share that knowledge with the community.

The first Singer factory in New York was a small workshop on Centre Street, above the old New Haven depot. Opened in the 1850s, it relied on handcrafting, so no two machines were exactly alike. Modern manufacturing systems like standardized gauges and assembly methods had not yet been introduced. Growing demand soon led Singer to move to larger, better-equipped premises in 1858.

In 1858, Singer moved from Centre Street to larger, better-equipped factories on Mott, Spring, Delancey, and Broome streets in New York. These sites operated until 1872, when production was consolidated at the new factory in Elizabethport, New Jersey.
Glasgow Love Loan (Scotland, UK)
Active from 1867 to 1869
Singer’s first Scottish factory opened in 1867 at 1 Love Loan, Glasgow, where about 30 workers assembled parts imported from the U.S. Early production was around 100 machines a month, but rapid demand led to relocation to a larger factory in James Street, Bridgeton, in the 1870s.

The Elizabethport (New Jersey, USA) factory opened in 1872 on a 32-acre site, becoming the world’s largest facility devoted to a single product. It replaced Singer’s smaller New York workshops and produced most early Singer machines. The plant survived a major fire in 1890 and contributed to both World Wars, manufacturing armaments and parts for Allied forces. By WWII it employed 5,000 people across 48 buildings on 113 acres, supplying parts and machinery to Singer factories worldwide. Civilian sewing machine production resumed in 1945 after the wartime halt. Output declined in the 1970s–80s, and the factory closed in 1982.

The Singer factory at Kilbowie, Clydebank, built between 1882–1885, became the largest sewing machine factory in the world, employing over 16,000 workers at its peak and producing more than 36 million machines. It featured a 200ft clock tower and advanced fireproof construction. The plant was key to Singer’s global dominance, though it faced major strikes in 1911 and heavy bombing during WWII. Modernized in the 1960s, it closed in 1980 after over a century of production; the buildings were demolished in 1998.
Other regional factories
Montreal (Canada)
Active from 1882 to 1906
Singer had a small Montreal (Quebec, Canada) factory from 1882 to 1906 at 2710 Notre Dame, likely used only for assembly from parts shipped from Elizabethport, NJ. Production in its last years was about 30,000 machines/year of models 15, 16, and 27. It was then replaced by a larger factory in Saint-Jean-sur-Richelieu (St. John), Quebec.

The Singer factory in Podolsk, Russia opened in 1902 to serve the Russian market and nearby countries. Initially, heavy stands were produced with imported machine heads, with the first fully local machine head completed in 1905. By 1914 the plant produced over 675,000 machines annually. During WWI and the 1917 Revolution, the factory was nationalised and continued production under state control. Post-WWII it was modernised with machinery from Wittenberge. Renamed Podolsk Engineering Plant and later Kalinin Sewing Machines, production declined in the 1960s–70s. Purchased by Semi-Tech in 1994 under the Singer brand, the factory finally closed around 2000.

What's next?
My research into Singer’s serial numbers, factories, machine characteristics and production history is necessarily an ongoing process. Many original records have been lost, others survive only in fragmentary form, and new information continues to surface through archival work, private collections and the efforts of dedicated researchers worldwide. For this reason, the material presented here should be seen as a living reference rather than a finished work.
This page, like all the other resource pages, will be updated over time as new data becomes available. I’ll do my best to refine my research, trying to identify and correct inaccuracies. If you notice errors, have additional information, or would like to contribute sources or insights, you are very welcome to get in touch or leave a comment below. Every correction or addition helps improve the overall accuracy and usefulness of our vintage sewing machine resources.
On my side, I will continue expanding and refining the serial number database, gathering and cross-checking as much reliable information as possible, with the aim of making it easier for anyone to trace the history of their Singer machine. My sincere thanks go to all the researchers, collectors and contributors whose work has made this whole project possible.
