The model number is on a plate or sticker on the machine body — not on the carry case, the manual cover or the box. On most modern domestic machines it is on the back near the power socket or on the underside; on vintage machines it is stamped on the badge, the base plate or the arm; on industrials it is a metal plate riveted to the arm. The name on the front (Heirloom, Anna, Designer, Innov-is) is the series, and several models share a series name, so look for the number, including any letters and suffix. Then type it into the search box and we show you every part the catalog confirms for it.
Why the exact number matters
A Singer 206K and a 206W take different bobbin cases. A Brother 1034D and a 1034DX share most parts but not all. A Bernina 475QE and a B475 take the same table — but the name on the front says only “475”. Suffix letters usually mean a market, a revision or an added feature, and the parts data names them separately where they differ. When you search here, enter the whole number as printed.

What else the plate tells you
Most plates also carry the serial number, the voltage and wattage, and sometimes a date code or a factory code. The voltage matters if you buy a foot control or a bulb — a 120 V control is listed as such — and the serial number is what Singer, Bernina and Pfaff use to date a machine. Photograph the whole plate; it costs nothing and answers the next question before it is asked.
Model number versus serial number
The serial number is unique to your machine and is the longer number, often on the same plate. Parts fit by model, not serial. On vintage Singers the serial number (two letters and six digits) dates the machine and identifies the model through Singer’s records, which is why old Singers are often identified by serial first.
Dating a vintage Singer from the serial
Singer serial numbers from 1900 onward begin with one or two letters followed by six digits, and Singer’s published allocation lists give the year and the model each batch was assigned to. If your Singer has only a serial number visible, send it with photos and we will look it up; the model it returns is what the parts data is keyed on.
If you cannot find it
- Photograph the machine from the front, the back and underneath.
- Photograph the part you are replacing, with a ruler in the picture.
- Email the photos to support@ultimatesewingandvac.com with any numbers you can see.
- We identify the model where we can and tell you which parts the catalog confirms.

Frequently asked questions
Is the model number the same as the serial number?
No. The model identifies the type of machine and decides which parts fit; the serial is unique to your unit.
The name on my machine says “Heirloom” — is that the model?
No, it is the series. Look for the number on the back or underside.
My vintage Singer only has a serial number. How do I find the model?
Singer’s serial records give the model from the two-letter prefix and number; send us the serial and a photo and we will identify it where we can.
Do the letters after the number matter?
Yes. K, W, D, E, QE and similar suffixes often change the parts. Enter the number exactly as printed.
Where is the model on an industrial machine?
A metal plate on the arm or front of the head, usually with the serial beside it.
Can I find the model from the bobbin case?
Sometimes — the case has a part number that narrows it — but photograph the machine too.
