Local phone numbers explained

How Rezi assigns a local number to each building, and how to request a specific area code.

Updated June 9, 2026 3 min read

Guests are far more likely to text a number that looks local. When you add a building, Rezi automatically provisions a phone number in your building’s area code.

The building number is the front door of the whole system: every text, every call, every workflow starts with someone contacting it. Three design choices make it work well, the number is local (familiar to guests, more likely to be answered and saved), it’s dedicated (one property, one number, zero ambiguity about which listing a message concerns), and it’s permanent (it stays with the property for as long as you run it, so it’s safe to print in your check-in instructions and welcome guide).

How assignment works

  • Rezi reads the building address and picks a number in the matching area code
  • Each building gets its own dedicated number, never shared between properties
  • The number handles both SMS and voice for that building

Provisioning happens automatically the moment you create the building, there’s no telecom paperwork on your side, no carrier account to manage, and no separate setup for voice versus text. The same number that answers a midnight “what’s the gate code?” text also answers calls with your building’s greeting. Rezi also handles 10DLC registration for the number, the carrier-required business registration that keeps your messages trusted and delivered.

Want a specific area code?

If your guests are concentrated in a different area code than the building address, you can request a specific one when creating the building. Contact support if you need to change a number after setup.

Putting the number to work

Add the property number to your check-in instructions, welcome guide, lockbox card, and the platform message you send guests. The more places it appears, the more Rezi deflects from your personal phone.

Treat the rollout like a small habit: include the number in the message you send guests when they book, print it on the welcome card in the place, and reply once to any guest who still reaches your personal phone (“text 555-0142 going forward, it answers instantly, day or night”). Hosts who do this see the bulk of traffic shift to the property number within a stay or two.

Keeping your personal number private

Once the property number is everywhere, your personal phone can finally retire from hosting duty. Guests never need to learn your direct line at all, escalations come to you through notifications, and when you reply to a conversation, the guest sees the property number, not yours. For what guests can and can’t see, read security and privacy.

Can I keep my existing well-known number?
The standard pattern is forwarding your old number to the new building number so nothing is missed. If you have a number guests deeply know and want to discuss porting it in, contact support@rezi-ai.com.
What happens to the number if I pause or close a building?
Pausing keeps the building’s setup intact, contact support about number retention timelines if you plan an extended pause. For permanent closures, give guests the replacement contact before the number goes dark.
Can one property have two numbers?
The design is one number per property. If you have a use case that seems to need two, contact support; often a single number plus smart routing covers it.
Do the numbers work for calls too?
Yes, every building number is voice-capable. Enable AI call answering per building to turn it on.
