Verify sends fail with 60203 'Max send attempts reached' while testing with one phone number

60203 Max send attempts reached

Verified 2026-10-15 · Confirmed by 0 builders · Trust 50/100

Cause

Verify allows five send attempts per verification lifecycle. Starting new sends without checking or cancelling keeps the same verification open until it expires.

Fix

Complete the lifecycle with a check, or cancel the verification in tests, or wait 10 minutes for it to expire.

Apply

await client.verify.v2.services(serviceSid).verifications(to).update({ status: 'canceled' });

Affects: Twilio Verify v2, checked October 2026
