Find Your Trimark Style Number: RN 137770, CA 19737 and the TM Item Number
Want more of the Trimark jacket, polo or tee you already have? The numbers on the collar will not get you there. RN 137770 and CA 19737 identify the company that makes Trimark apparel, not your garment. The number that does is the style number on the small care label sewn inside. This page shows where to find it and how to turn it into a reorder with your logo.
Watch: reading a Trimark label in under a minute
Two labels, two jobs
Most Trimark garments carry two labels. Only one of them tells you which style you are holding.
| Label | Where to look | What is printed on it | Good for a reorder? |
|---|---|---|---|
| Collar label | Inside the back neck | TRIMARK, MEN’S/HOMMES or WOMEN’S/FEMMES, size (for example XL/TG), country of origin, CA 19737, RN 137770 | No. These details are identical on thousands of different Trimark items. |
| Care label | Side seam on tees and shirts, inside the lining on jackets and vests, near the collar on some knits | STYLE #, PO#, VN#, fabric content, care instructions | Yes. The STYLE # is the number you need. |

From the label to this catalog: add TM
On the care label the style number is just five digits, for example STYLE # 16398. In our catalog every Trimark item is listed with a TM prefix, so that label matches TM16398. You can type either version below. Each product page also shows it under Item Number in the description.
Numbers on the label that are not the style number
- RN 137770 is a Registered Identification Number from the U.S. Federal Trade Commission. It names the manufacturer and importer behind Trimark, so it is the same on every item in the line. Some Trimark labels show RN 133060, another company identifier that works the same way.
- CA 19737 is the Canadian counterpart of the RN number. It also identifies the company, not the product.
- PO# and VN# on the care label are production and factory codes. They change from batch to batch and will not match anything in a catalog.
- XL/TG, MEN’S/HOMMES and WOMEN’S/FEMMES are the size and fit in English and French, because the same garments are sold in the U.S. and Canada.
Tips that save a phone call
- Some care labels list two style numbers. Search for each one, as only one of them is usually the catalog number.
- Men’s and women’s cuts of the same Trimark design have different style numbers. If your search shows the right garment in the wrong fit, open the other version from the category page.
- Trimark gives each style a name, printed in capitals in our product titles, such as COLTER, KRUGER or HARDY. If you remember the name from the hang tag or an old order, search for it.
- No label left? Search by what the garment is, for example quarter zip, insulated jacket or beanie, or browse the product categories and compare the photos.
Still not sure? We will identify it for you
Our research team matches discontinued, renamed and unlabeled Trimark styles every day. Send us a photo of the front of the garment, a photo of any label that is left, and the color, and we will tell you exactly what it is and quote the reorder with your logo embroidered or printed.

Trimark label questions
Can I reorder a Trimark item using RN 137770?
Not on its own. RN 137770 is printed on every Trimark garment regardless of style, color or size, so it only confirms the brand. Use the STYLE # from the care label, or send us a photo.
What does CA 19737 mean on my shirt?
It is the CA identification number required on textile labels sold in Canada. Like the RN number, it belongs to the company behind Trimark and does not identify a single product.
Where is the style number on a Trimark jacket?
Open the jacket and check the inside lining, usually along a side seam or inside a pocket. On tees and button-up shirts it is in the side seam; on some knit polos it is close to the collar.
Is the TM number the same as the style number?
Yes. TM is simply the prefix used in our catalog. STYLE # 17743 on the label is listed here as TM17743, and searching for either finds the same product.
Can you put our logo on the same Trimark style we bought before?
Yes. BrandedItems is an authorized Trimark distributor. Once we know the style, we match the color and sizes and embroider or print your logo, and we keep your artwork on file for the next reorder.
