What is Пин-сабмит (PIN Submit)?

PIN Submit is a registration or payment step where the user enters a one-time PIN code received by SMS into a form on a landing page or in a widget. The code confirms that the phone number belongs to the user and that they agree to the subscription or charge.

## How it works

First the user enters a phone number, then the operator or provider sends an SMS with a code. PIN submit is the step where the entered code is sent back to the system, after which the request goes to billing. If the code is wrong or expired, the step is repeated, and some offers limit the number of attempts.

## Where it is used

PIN submit is most often used in dating offers with mobile billing and in subscription products where payment is charged to the phone account. A similar logic exists in cc-submit, where card details are entered instead of a PIN, and in two-factor verification, but there the code confirms login, not a charge.

## What it affects

PIN submit directly determines conversion into a subscription. A low share of entered codes usually means problems with SMS delivery, an inconvenient interface, or extra fields in the form. Affiliates should measure conversion from click to successful submit, not only up to entering the phone number.

## Common mistakes

SMS delays, an incorrect phone number mask, no clear text about subscription terms, and attempts to bypass the confirmation required by the operator. The last one leads to traffic blocks, chargebacks and user complaints.
