FAQ

Questions about phone carrier lookup

Type the number with its country code in the box at the top of this page. The lookup returns the carrier when the provider has it, along with the line type and region.

Yes. Each lookup in the box costs you nothing and is limited per hour. For a list of numbers, your agent runs the same lookup from your own looot account at the per-call price shown above.

The provider does not have a carrier name for every number, and numbers moved to another carrier may show the old one or none. The line type and region still come back.

Yes, when the number range says so. In some countries, such as the US, mobile and landline numbers share ranges, so the answer reads landline or mobile.

Start with + and the country code, such as +44 20 7946 0000. Spaces, dashes and brackets are fine. Without the +, fill in the two letter country code.

No. It reads numbering data only. Nothing is sent to the phone.

Give your agent the skill.md link from the prompt above. It calls the tomba-phone-validator endpoint with the phone field, and country_code when the number has no +, then reads the result.

Yes, from your agent. One call covers one number and the agent loops over the list, then shows the total cost.
