There's nothing worse than seeing your phone buzz, picking up and realizing it's a robocall, where someone is trying to dupe you into giving up your bank and credit card information. With tax season coming up, you can expect even more of those calls to start coming.

A record 5.2 billion robocalls were placed last month, according to YouMail's robocall index, and 58 percent of them were scam or telemarketing calls. That includes 54 million robocalls in New Massachusetts, an average of 6.6 for every person in the state. Here are the top 20 robocallers in Masschusetts last month, showing the number, place of origin if known, the carrier, the caller ID and the type of call.

Medical Customer Call YouMail's index showed that residents in Baton Rouge were bombarded with robocalls last month, ranking No. 1 in the country, with a staggering 58.4 robocalls per person. Washington, D.C. residents saw the second-highest number of calls, at 51.6. Here are the 10 cities receiving the most calls per person:

Baton Rouge, LA — 58.4 robocalls per person Washington, D.C. — 51.6 robocalls per person Memphis, TN — 42.3 robocalls per person Macon, GA — 37.4 robocalls per person Lafayette, LA — 33.3 robocalls per person Little Rock, AR — 33.3 robocalls per person Birmingham, AL — 31.5 robocalls per person Albany, GA — 31.5 robocalls per person Las Vegas, NV — 31.2 robocalls per person Shreveport, LA — 30.9 robocalls per person YouMail says the nationwide rise coincides with a "search listing scam," where robocallers dupe small business owners into giving up credit card information. The scammer promises to boost the business' ranking in Google search listings. And with more and more tax filers sending their returns to the IRS, don't expect scam robocalls to decline anytime soon.

In fact, a new report from the data communication network company Transaction Network Services found that April 17, 2018 — Tax Day — saw more negative robocalls than any other day of the year. That month saw the highest volume of the year. The researchers noted that call spoofing — when scammers change their caller ID so they match your area code — remains the go-to tactic for bad actors. One in every 4,000 phone numbers was hijacked by a spoofer, the company found.

Bill Versen, chief product officer at the company, said consumers need to be "especially vigilant" as Tax Day approaches, and keep their guard up.

The FCC offers a few tips for those wanting to stop unwanted and illegal robocalls. Among them, don't answer calls from unknown numbers, do not respond to questions — especially those that can be answered with "yes" — and never give out personal information such as account numbers, Social Security numbers and mother's maiden names.
