Czech business phone number

Czech businesses need a reliable company number for calls, SMS and WhatsApp — without managing CPaaS consoles. Atly provisions Czech SKUs from live Twilio catalog entries with honest channel capabilities.

What Czech businesses use Atly for

• One firemní číslo connected to inbox and calendar
• WhatsApp Business on the company number (self-serve WABA)
• SMS where the purchased mobile or local SKU supports it
• AI drafts with human approval before customer replies go out

Channel reality in Czechia

WhatsApp is available on Atly company numbers. Voice and SMS depend on the SKU you purchase. Some setups need two numbers — for example a Twilio mobile SKU for SMS and WhatsApp plus a local number for voice. The setup wizard shows last-seen caps from the catalog.

Operator and data

Atly is operated by AtlyTech s.r.o. (Praha, IČO 29944627). Product infrastructure targets EU-oriented storage. See [Trust](/trust) for security and data handling.

Porting

Number port-in is available only where the catalog marks the SKU as portable. Check the company-number wizard for current status — do not assume every Czech number type can port today.

Getting started

Demo and Trial are available at [atly.work](/). Setup runs in Czech through the locale switcher.
