Why private label sellers choose third-party barcodes
GS1 charges $250+/year for a company prefix — and that's before you know if the product has legs. For a private label seller testing a new product, that's a meaningful cost that doesn't go away if the product doesn't sell. UPCBay codes are one-time. You pay $8 for a code, the product either works or it doesn't, and there's no recurring cost either way.
What about the GS1 requirement debate?
The debate comes up because Amazon and some retailers have said they prefer GS1-sourced GTINs. In practice, codes from original UCC-issued prefixes (which predates the current GS1 system) work on Amazon for the vast majority of private label use cases. The codes are traceable, legitimate, and create real listings. Where GS1 matters is large brick-and-mortar retail — Kroger, some Walmart programs, and similar. If that's not your current plan, third-party is fine.
How to structure barcodes for a private label catalog
One code per SKU. If you launch with five products, buy five codes. If you add variants (sizes, colors), each variant is a separate code. Keep a simple spreadsheet mapping each UPC to its product and variant — you'll need this for Amazon catalog management anyway.
Package recommendation
Most private label sellers testing 1–3 products start with the 5-code bundle at $15. Scaling to a real catalog? The 100-code bundle at $45 (under $0.50/code) is the most cost-efficient.
