(531) Area Code Business Phone Numbers
The 531 area code is the overlay for eastern Nebraska, introduced in 2011 to sit alongside the long-running 402. If you want a phone number that sounds like Omaha, Lincoln or anywhere between, this is the one to grab.

The 531 area code arrived in 2011 as an overlay for the entire eastern half of Nebraska, taking in Omaha, Lincoln, Norfolk, Hastings and the smaller towns in between. It shares every bit of ground with 402, which has been around since 1947, so to a local the two codes feel like one and the same.
Omaha punches well above its weight on the business map. Four Fortune 500 companies call it home, including Berkshire Hathaway, Union Pacific, Kiewit and Mutual of Omaha[1]. Around them sits a thick layer of smaller shops, insurance offices, trades, logistics firms and tech startups, with Nebraska's statewide unemployment rate holding at the sixth lowest in the country in 2025[2].
A 531 number tells customers you are nearby, which matters when a plumber or a clinic is picking who to call back first. Tonet gives you a real local number that works from your laptop, your phone or a desk phone on your counter, with no contract and no setup fees.

Frequently Asked Questions
Can I still get a 531 number if I live outside Nebraska?
Yes. Numbers are bought in the dashboard by area code and work on the browser, the mobile app or a desk phone wherever you are. Nothing about 531 ties you to a Nebraska address.
Is 531 the same calling area as 402?
Pretty much. 531 was added in 2011 as an overlay for the same ground 402 covers, so Omaha callers dial ten digits for either one and the local feel is identical.
Can I port my existing 531 or 402 number to Tonet?
Yes, porting is free. Most ports complete in 7 to 10 business days, sometimes longer depending on your current carrier. Your number keeps working with the old provider until the switch, so there is no downtime.
How much does a 531 number cost each month?
Plans start at $10 per user per month billed daily. The number itself is $2.50 per month. There are no contracts, no setup fees and no seat minimum.
Will my 531 number work for verification codes from banks or apps?
A Tonet number is a VoIP number. It usually does not work for banking-style 2FA, and it is case by case elsewhere, so do not count on it. A US SIM is the dependable route for that kind of thing.
