CodeClassify is a suite of 16 free, browser-based tools plus a deterministic REST API and downloadable CSV datasets for validating, converting and classifying product and business codes: GTIN/UPC/EAN barcode check digits, ISBN, IBAN (MOD-97), EU VAT, VIN, SSCC pallet codes, ISO 6346 containers, ABA routing numbers, and business classifications (NAICS 2022, SIC 1987, the SICโ†”NAICS crosswalk and HS customs codes).

Every result is computed from official public standards (GS1 Mod-10, ISO 13616, U.S. Census, U.S. HTS) โ€” the same input always returns the same output, with no AI guessing. The free tools need no sign-up and run entirely in the browser; the API and datasets handle bulk validation and automation.

Questions & Answers

As answered by people managing iA Writer and CodeClassify.

How would you describe the primary audience of your product?

CodeClassify's answer:

E-commerce sellers & ops validating GTIN/UPC/EAN before listing on Amazon, eBay or Shopify

Developers & data engineers needing a deterministic API for bulk validation and classification

Accountants & analysts working with NAICS/SIC business codes

Logistics, customs & trade teams handling HS codes, SSCC pallets and ISO 6346 containers

Finance/fintech teams checking IBAN, EU VAT and routing numbers

What makes your product unique?

CodeClassify's answer:

CodeClassify is deterministic: every result is computed from official public standards (GS1 Mod-10, ISO 13616, ISO 3779, U.S. Census NAICS/SIC, U.S. HTS), so the same input always returns the same output โ€” no AI guessing, no invented codes. It's also unusually broad: one place to validate, convert and classify barcodes (GTIN/UPC/EAN), ISBN, IBAN, EU VAT, VIN, SSCC, ISO 6346 containers, ABA routing numbers, and business codes (NAICS/SIC/HS) โ€” as free browser tools, a REST API, and downloadable datasets.

Which are the primary technologies used for building your product?

CodeClassify's answer:

CodeClassify runs on Cloudflare Pages for the static tools and Cloudflare Workers + D1 for the API and dashboard. The validation and classification logic is implemented directly from official public standards and datasets (GS1, ISO, U.S. Census, U.S. HTS). Payments are handled by Stripe, and the API is also distributed on RapidAPI.

Why should a person choose your product over its competitors?

CodeClassify's answer:

Most alternatives are single-purpose (just barcodes, or just IBAN) or AI-based classifiers that can hallucinate codes that don't exist. CodeClassify covers every major product and business code in one place, computes results from official standards (auditable and repeatable), and offers three ways to use it: free tools with no sign-up, a deterministic API for bulk and automation, and clean CSV datasets. It's built for feeds, compliance and data pipelines where "the same answer every time" matters.

What's the story behind your product?

CodeClassify's answer:

CodeClassify started from a simple frustration: product and business codes are everywhere, but checking them meant a dozen scattered, ad-heavy sites โ€” and newer "AI" tools would confidently return codes that don't exist. The goal was one clean, fast place that computes every answer from the official standard, keeps the everyday tools free and sign-up-free, and offers an API and datasets for teams that need to work at scale.
