Equifax Rate Limits

Equifax does not publish public per-second or per-minute rate-limit numbers. Its developer portal confirms HTTP throttling and standard error responses, but actual quotas are set per-customer contract and provisioned at the API key/credentials level. Sandbox and production environments are separated.

Policies

Sandbox vs production
Use sandbox credentials for integration testing; production credentials carry FCRA-permissible-use attestations and stricter audit logging.
Backoff
On 429 / 503, apply exponential backoff with jitter; do not retry idempotent reads aggressively as inquiries can post to the consumer's bureau record.
Inquiry minimization
Cache permissible-use results where regulation allows to minimize repeated bureau pulls against the same consumer.
