Substack prices by country

Cheapest first, because choosing a country is how you choose a price. Every figure is retail — the one your wallet would be debited — and every row has stock behind it. The delivery rate is the carrier’s own historical figure for that pair, shown as reported and left blank when it is not.

One code, then it is gone

A Substack activation is a number rented for a single verification. You see the exact price before you confirm, and the wallet is debited for that figure and no other.

Refunded if nothing arrives

No code, no charge. A cancelled or expired activation is refunded to the wallet automatically, and the refund is a row in the same ledger as the debit.

Or keep a line for Substack

A dedicated US or Canada business number from $0.50/mo receives Substack codes month after month — plus SMS and calls for every other service you sign up for. Dedicated lines are self-serve — search inventory, confirm the exact price, and pay from your wallet. Inbound SMS lands on the number’s thread in the dashboard.
