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 SICโNAICS 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.
Trustpilot CodeClassifyTrustpilot is recommended for consumers who want to research businesses before making a purchasing decision and for businesses aiming to engage with their customers, improve their services, and enhance their online reputation.

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
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.
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.
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.
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.

Motivate users to write reviews According to a survey by the First Page Sage Agency, online reviews impact AI chatbots' responses from 13 to 31%. This means that your reputation on TrustPilot or Capterra has a big impact not only on users who look through these platforms before making a purchase, but also on AI Models. As a brand, you can motivate people to write reviews by notifications or bonuses. - Source: dev.to / 11 months ago
After that, the journey to the hell started: - We clicked on the refund option (there was only a single choice) and it was written in small letters at the bottom, hiding that the money will not be returned, but a "credit" will be provided to be used within 2 years. - Obviously, I didn't like it the credit idea because I wanted the plane ticket or my money back. - the customer service recommended to book it...

So we're all going to be scrambling for alternatives. Please check trustpilot.com before you order. Semaspace had good reviews there. A lot of the alternatives do not. Hoping to find a company that's not going to rip me off. Source: over 2 years ago
Research and check for legitimate reviews on platforms like trustpilot.com. Lack of reviews or an influx of recent ones could indicate a scam. Source: almost 3 years ago
I wouldn't know about that website but I can tell you that zenbu-pharma.com is definitely legit. I've used them several times and they have great reviews on trustpilot.com. Source: about 3 years ago
