Why Did I Receive a Call From 504?

There are a few reasons why your phone may ring with a 504 area code caller on the other end:

Local Business

With 504 covering New Orleans and other major commercial areas, many local businesses use phone numbers with this area code. So it could be a local store, restaurant or other service calling.

Scam Call

Unfortunately, spammers and scammers often spoof local area codes to try tricking users into answering. Some common 504 scam call topics involve suspicious credit card activity, fraudulent tax warrants and more.

Telemarketer

Telemarketing calls can also come from 504 numbers, often pitching various products, services or donations. These types of calls typically ramp up around tax season.

Robocall

Automated robocalls programmed to play a prerecorded message have also been known to use the 504 area code, even if the company itself has no Louisiana connection.

Friend or Family

Of course, the person calling from a 504 number could also be someone in your personal life originally from southeastern Louisiana.

The call’s origin doesn’t necessarily indicate if it is legitimate or not. Scammers spoof area codes, while legitimate businesses may use toll-free 800 numbers. Look at the full phone number to determine if it’s suspicious.

Tips for Identifying Legitimate 504 Calls

How can you discern fraudulent 504 calls from valid ones? Here are tips:

  • Let unknown numbers go to voicemail
  • Research the full number
  • Verify claims before providing personal information
  • Register your number on the National Do Not Call Registry
  • Consider call blocking apps and services

Carefully scrutinizing unfamiliar 504 callers before answering or providing personal details can help avoid falling victim to thieves hoping to take advantage of those with ties to the region. Only engage with calls you can confirm are authentic.

Why Use a 504 Phone Number for Business?

Why Use a 504 Phone Number for Business?

Local phone numbers are tremendously valuable for businesses in the 504 region targeting customers in those areas. Seeing the 504 area pop up on caller ID helps instill consumer confidence that they are working with a trustworthy local company dedicated to serving southeastern Louisiana.

Additionally, local phone numbers tend to rank higher in local search results pages. So using a 504 phone number with a New Orleans area address on a business website can help drive more organic traffic from nearby searchers.

The 504 area code has a long history with Louisiana. Both residents and businesses are proud to continuing using it to this day.

The Future of the 504 Area Code

The 504 area code has seen incredible demand growth over its 75+ year lifespan, resulting in the need for multiple area code splits and overlays.

So what does the future look like for the 504 region?

Continued increasing phone number demand is expected as population and business growth remains strong in southeastern Louisiana. Both New Orleans and Baton Rouge continue attracting new residents and companies.

An additional area code overlay may eventually become necessary if the addressable pool of available 504 and 985 numbers starts dwindling too far.

For example, California’s 310 area code has had at least 10 area code overlays approved over the past 30 years to supplement the desired 310 phone numbers.

While 504 números remain plentiful for now, another area code overlay could happen in the coming years or decade if need be.

Some other possibilities down the road include:

  • Reshuffling 504 region boundaries by cutting parishes currently in the 504 zone into a new area code territory
  • Mandatory 10-digit local dialing to enable more number assignments. Currently 7-digit dialing is widely used for local 504 calls.

Of course Louisiana phone subscribers would likely push back on major changes to the historical 504 area code they know and love.

Time will tell how area code administration adapts to demand trends in the coming years.
