Why Use a Temp Number for Substack?
Substack uses phone verification as an optional but increasingly common step for publisher account creation, particularly for newsletters that intend to charge subscribers. Verifying a phone number on Substack unlocks the ability to enable paid subscriptions and increases the account's trust score within Substack's fraud-prevention system. United States numbers generate the most Substack verifications on TempNumber.me — Substack is primarily a US market product and US numbers from major carrier ranges are natively trusted by the platform.
Substack's paid subscription model means the platform is cautious about account fraud. Phone verification signals that a publisher is a real person, which Substack uses to approve access to Stripe payment integration. A temporary US number can complete this verification step, after which the Stripe payout account is set up separately with real banking credentials.
Best Countries for Substack Verification
- United States — The primary Substack market. US numbers (+1) from AT&T, Verizon, and T-Mobile ranges produce the highest Substack verification success rates and unlock full US publisher features including Stripe USD payouts.
- United Kingdom — UK numbers work for Substack and are accepted for publishers targeting UK audiences. British numbers (+44) are accepted with reliable OTP delivery.
- Canada — Canadian numbers (+1) work for Substack's North American platform, sharing the same NANP code as US numbers.
Tips for Successful Substack Verification
- Substack OTP codes expire in 10 minutes. Enter your temporary number on Substack first, then switch to TempNumber.me to wait for the SMS.
- After phone verification, set up your Stripe account using real banking details — the temporary number only covers the SMS verification step, not the payment processor identity verification.
- US numbers are preferred for Substack if you intend to accept USD subscriptions, as Substack's Stripe integration defaults to the account's phone number region for currency selection.
