Two ways to get a number: let Linxi provide one, or connect your own carrier
Search & Buy a Number in Linxi gets you a managed number with the carrier and A2P registration handled for you. If you connect your own Twilio account instead, the Twilio steps here follow Twilio's redesigned console at 1console.twilio.com as it was when they were written; Twilio may move things since.

How to Buy a Twilio Phone Number

Once your Twilio account exists, buying a number takes about a minute. Here's what to search for and what to look for in the results.

â„šī¸ No Twilio account? You can buy a number inside Linxi instead: Linxi Settings → Number → Linxi Number → Search & Buy a Number. Linxi buys it on Telnyx for $1.50/month (the first number is included on paid plans), handles the A2P registration, and bills it on your Linxi account. The steps below are only for buying a number in your own Twilio account.
1

Find the number search page

In the console's left sidebar: Products and services → Communications → Numbers and senders, then Overview (or go directly to Phone Numbers → Buy a number). This is where you search Twilio's available inventory.

2

Search by area code or pattern

You can search by area code (e.g. 561 for South Florida) for a locally-recognizable number, or by a vanity digit pattern if you want something memorable. Local (not toll-free) numbers work best for two-way conversational SMS.

3

What capabilities to look for

Make sure the number shows both SMS and MMS capability badges in the search results — not every number supports MMS, and Linxi's Compose & Send can attach images to campaigns. Voice capability is optional today. Calling in Linxi is coming, so if you think you'll want it, pick a number that also shows Voice.

4

Cost

A local US number ran about $1.15/month on Twilio at the time of writing, billed to whatever payment method is on your Twilio account. This is separate from, and in addition to, any Linxi subscription — on your own account, Twilio bills you directly for the number itself and for every message segment sent/received. A number bought through Linxi is billed by Linxi instead; see Pricing.

5

E.164 format

Once purchased, your number will be shown as something like +15615550142 — that's E.164 format: a +, the country code (1 for the US), then the 10-digit number with no spaces, dashes, or parentheses. This is the exact format Linxi Settings → Number → Linxi Number expects when you enter the number later.

💡 Choose an area code that matches your business's physical location where possible — recipients are noticeably more likely to answer or engage with a number that looks local to them, and it can modestly help deliverability with some carrier filtering.
✅ Messages are billed at carrier cost. Linxi does not mark up SMS or MMS — $0.004 per SMS on Telnyx, $0.0079 on Twilio, the same as the carrier charges. See Pricing — Sends at Cost for the full breakdown.
