Requirements depend on the country and number type. For most destinations, a company name and contact details are sufficient; for some countries, regulators require proof of address or business registration documents. Before ordering, your account manager will provide the exact list for your chosen country.

Numbers are activated within a few hours after payment. If document verification is required for a country or the number is ordered for a specific city, the timeframe is 1 to 3 business days. Your manager will confirm the exact timeline when you submit your request.

Yes, in most countries numbers tied to a specific city or region are available — this helps build local presence and increase answer rates. Availability depends on the location you need: tell your manager the city you want, and we'll find a number or suggest the nearest alternative.
