Plenty of sweepstakes still ask you to call a number or text a keyword to a short code to enter. Radio-station giveaways, in-store "text WIN to 12345" promos, and county-fair drawings all run on phone entry. The catch: the moment you hand over your real cell number, it lands on marketing lists, and the robocalls and promo texts follow you for months. The fix is a free second number that soaks up all of it while your real line stays clean. 📞
Set up a free Google Voice number in about 10 minutes
Google Voice gives any US resident with a Google account one free phone number, and it's the workhorse for sweepers. Go to voice.google.com, sign in, click "For personal use," and pick a number — you can search by area code, so choose one that matches your region if a sweep requires an in-state entrant. Google will ask you to link one real existing phone to verify the account; that's a one-time step and your real number never gets exposed to the sweep.
Once it's live, the number works for both voice and SMS. You can call the radio station's contest line straight from the Google Voice app, and you can text a keyword to most five- or six-digit short codes. One honest limitation: a small share of short-code campaigns block Voice-over-IP numbers, so if a text bounces back undelivered, that sweep needs a "real" carrier line. For the other 90%, Voice works fine and costs nothing.
Route it to your inbox so you never miss a win
The whole point of a second number is that you can ignore it day to day but still catch the message that says you won. In the Google Voice app, open Settings → Messages and turn on "Forward messages to email," and under Voicemail, enable voicemail transcripts to email. Now every entry confirmation, every "you're a finalist" text, and every voicemail lands in your regular inbox as searchable text — no need to open a separate app.
Take it one step further and build a filter. In Gmail, create a filter for messages from txt.voice.google.com and apply a label like "Sweeps-Phone" so they skip the clutter and stack in one place. When a winner notification arrives with a claim deadline — often just 24 to 72 hours — you'll spot it fast instead of digging through a neglected app. That speed matters, because unclaimed prizes get redrawn.
Contain the spam before it starts
Even a throwaway number attracts junk, so cage it from day one. Inside Google Voice, go to Settings → Security and switch on "Screen calls" and filter spam — Google auto-sends flagged robocalls straight to voicemail, and you can silence unknown callers entirely. Any number that harasses you can be blocked in two taps, and because it isn't your real line, you never worry about a legit contact getting caught.
The bigger habit is legal protection: read the entry terms before you text. That "text to enter" keyword often doubles as opt-in consent to recurring marketing messages. US short-code rules require the sponsor to honor STOP — reply STOP to any unwanted campaign and they must cease texting. Keep your entries on the burner number, reply STOP the second a promo turns pushy, and your real phone stays quiet all season.
