LookupTax Alternative — TaxID
LookupTax is built for companies that validate tax IDs globally — US EINs, Brazilian CNPJs, Australian ABNs, and EU VAT in one API. If that's your use case, it's a strong product. But if your scope is EU VAT only, you're paying for global coverage you don't use. LookupTax starts at $29/month for 10,000 validations. TaxID covers all 27 EU member states at $19/month for the same volume — with a 100-request free tier and a self-service signup that takes two minutes.

Why developers switch from LookupTax
LookupTax limitations
- Higher price point than EU-only alternatives
- Overkill if you only need EU VAT validation
- Free tier only 50 requests/month
- More complex API surface area for EU-only use
TaxID advantages
- EU-specialized: faster and cheaper for EU-only use cases
- $19/month for 1,000 validations vs LookupTax's $29/month entry point
- 100 free requests/month vs LookupTax's 50
- Simpler API surface — one endpoint for EU VAT, no global routing logic
- Self-service signup: API key in 2 minutes, no onboarding call
When to choose LookupTax instead
LookupTax is the right choice if you need global tax ID validation beyond EU: US EINs, Australian ABNs, Brazilian CNPJs, or Canadian BNs. TaxID is EU-only and will not help you there. LookupTax also offers official SDKs (Node.js, Python, PHP), formal SLA agreements, batch validation, and webhooks — all features TaxID doesn't currently have. If your compliance team requires any of these, LookupTax is worth the premium. For EU-only validation at startup-to-growth scale with a developer-led team, TaxID is the leaner, cheaper option.
Switching from LookupTax to TaxID
The core change is the endpoint URL and authentication header. Both APIs return company_name, valid, and company address — no downstream code changes needed for the core validation logic.
GET https://api.lookuptax.com/v1/validate/EU-VAT/DE/DE123456789 (Header: Authorization: Bearer ltax_xxxxx)
GET https://taxid.dev/api/v1/validate/DE/DE123456789 (Header: Authorization: Bearer vat_xxxxx)
LookupTax uses /v1/validate/EU-VAT/DE/number path; TaxID uses /api/v1/validate/DE/number. LookupTax returns entity_name; TaxID returns company_name. Bearer auth token format is the same.

Frequently asked questions
Does TaxID support global tax ID validation like LookupTax?
No. TaxID validates EU VAT numbers only — all 27 EU member states via the VIES system. If you need to validate US EINs, Australian ABNs, Brazilian CNPJs, or other non-EU identifiers, LookupTax (or a similar global provider) is the right tool. TaxID's EU specialization means it's faster and cheaper for EU-only workflows, but it is not a like-for-like replacement if you need global coverage.
Does TaxID have official SDKs like LookupTax?
Not currently. TaxID's API follows standard REST conventions (Bearer auth, JSON responses, HTTP status codes), so integrating with any HTTP client in any language takes under 10 lines of code. The documentation includes examples for Node.js, Python, PHP, and curl. If typed SDK wrappers are a requirement for your team's workflow, LookupTax has the advantage.
How does LookupTax's pricing compare to TaxID for EU-only use?
For EU VAT only: LookupTax starts at $29/month for 10,000 validations. TaxID's Growth plan is $49/month for 10,000 validations — slightly more expensive at that tier. However, TaxID's Starter plan covers 1,000 validations for $19/month, and the free tier covers 100/month. If your volume is under 1,000/month, TaxID is significantly cheaper.
Does LookupTax have an SLA?
Yes — LookupTax offers SLA guarantees, which TaxID does not currently provide. If your enterprise procurement or compliance team requires a formal SLA, LookupTax is currently the better choice for that requirement.
