Bluesky asks many new accounts to verify by phone to curb spam signups. If your own number can’t receive the code, or you want to sign up with an overseas number, you can finish verification with a number that receives SMS. Follow the steps below.

Why Bluesky asks for a phone number
- Anti-spam: a phone number confirms a real person and limits bulk registration.
- Virtual / VOIP numbers get rejected: prefer a real SIM, see Real SIM vs virtual numbers.
- One number, one account: a number is usually tied to a single Bluesky account at a time.

Step 1: Pick a country close to your network
Keep the number’s country near your network environment; a real SIM clears far more reliably than a virtual number.
Step 2: Order a number
curl -X POST https://api.simsmsbox.com/api/sms/orders/purchase -H "X-API-Key: psk_xxx" -H "Content-Type: application/json" -d '{"service":"bluesky","country":"US","cardKind":"physical","rentDays":30}'
# -> { "orderId": 74, "phone": "+1xxxxxxxxxx", ... }
Step 3: Enter the number and request the code
Enter this number in Bluesky’s verification step and request the SMS code.
Step 4: Poll to retrieve the code
curl https://api.simsmsbox.com/api/sms/orders/74 -H "X-API-Key: psk_xxx"
# -> { "status": "received", "latestCode": "264193" }
For cadence, see Automated ordering and polling — query every few seconds after ordering, don’t hammer it.
