Is it a premium-rate number?

Purpose

Find out whether a number or prefix is premium rate, shared cost, directory enquiries or a missed-call scam code, what calling it costs and whether to call back.

Requirements

Anyone can read these guides, no account needed. Some tools require Pro, as indicated in each guide.

Type a number or a prefix such as 806, 905 or 118. We tell you what kind of special number it is, what calling it usually costs and whether calling back is risky.

Premium rate: A paid service: entertainment, contests, adult content or professional advice. The service sets the price. Far more than a normal call, charged per minute or per call, and never included in a flat rate.

Mass calling and televoting: A range for television votes and contests that receive many calls at once. A fixed price per call that is higher than a normal call.

Directory enquiries (118xx): Directory services that look up and connect numbers. A high connection fee plus a high price per minute; they can put you through to another number while still charging.

Shared cost: A company number where you pay part or all of the call. Usually more than a normal call, and many plans do not include it.

Personal number: A number that forwards calls to another line chosen by its owner. Depends on the operator and is often higher than a normal call.

Commercial calls (400): Spain’s range for sales calls since 17 October 2026. These numbers only make calls. None: operators must block calls to 400 numbers, so there is nothing to pay.

Freephone: Customer-service numbers that are free for the caller. Free from landlines and mobiles.

Satellite or global network: Satellite phones and global networks with their own calling code. Among the highest per-minute rates there are.

Missed-call scam code (wangiri): A calling code that keeps appearing in international missed-call campaigns that try to get you to call back. Charged as an expensive international call; part of it can go to whoever set up the number.

International number: A number from another country. Charged as an international call by your operator.

Ordinary landline or mobile: Not a special-rate number. Like a national call; it is usually in your plan.

Not recognised: We can’t classify this number. Check the price with your operator before calling.

Limitations

Indicative information from published numbering plans. It describes the type of number, never the person or company behind it.

Troubleshooting

If the input is invalid, check its format and country. Retry connection errors; respect the waiting period when a limit is reached.

Enter a valid phone number or prefix.
