How do i get google to recognize my cell phone when people want to send me a code?

****

i'ms selling items on Marketpace and Offer up. People are suspicious i am a bot so they try to send me a google code to my cell phone number. Google says it cannot be verified. How do i get Google to recognize my phone number so people can verify i am a real person.

Do they ask you for Google Voice verification code?

****, it's probably scamming.
Never provide anyone with your Google Voice verification code. Upon receiving this code, the scammer can use your phone number to create a Google Voice account for themselves linked to your number
Keeping your phone number private online is essential.
NEVER reveal any verification codes to anyone!
NEVER clicking links or attachments from unknown sources is the key to cybersecurity.
