validate_gtin — Validate a barcode number — EAN-13, UPC-A (12), EAN-8, or GTIN-14 (keyless, offline). Checks the mod-10 check digit, reports the format, normalizes to GTIN-14, and returns the GS1 prefix + issuing country/region. Spaces/dashes ignored. Validates the number, not the product.
gtin_check_digit — Compute the mod-10 check digit for GTIN/EAN/UPC data digits (all digits EXCEPT the check digit). Use to generate or repair a barcode.
