# PINs

> Let payers call from another phone with a 4-digit Paid Calls PIN. How PINs are issued, shown once, entered on the call and locked after 3 wrong tries.

By default, a paid call works only from the mobile number the caller entered when paying. Turn on **PINs** to let them call from a different phone, for example a parent who pays for a student.

## How it works

1. Turn on the PIN option in the page settings ("Callers get a 4-digit PIN after paying; from another phone they key it in").
2. After paying, the caller sees a **4-digit PIN** on the success screen: "Paid from another phone? Enter this PIN when asked." It is shown only once.
3. When they call from a number that hasn't paid, they are asked for the PIN and key it in.
4. The right PIN connects the call for that payment's minutes.

| Rule | Detail |
|---|---|
| PIN length | 4 digits, unique among the unused payments on your number |
| Shown | Once, right after payment |
| Wrong tries | 3 wrong PINs within an hour lock that caller out for a while |
| Default | Off |

## When to leave PINs off

PINs are off by default. With PINs off, unpaid callers are refused before the call is answered. With PINs on, a caller from an unknown number is answered so they can enter a PIN, and a refused caller is then disconnected after the message. If your callers always pay and call from the same phone, keep PINs off.

## FAQ

**The caller lost their PIN. What can I do?**
The PIN isn't shown again. Grant the caller a call by hand for the number they are calling from; see [Packages and Validity](https://edesy.in/docs/paid-calls/calls/packages-and-validity).

**Does the PIN work after the payment expires?**
No. A PIN belongs to one payment and works only while that payment is valid and unused.
