Here are some websites I use when doing SSA or IRS calls in order to have information on hand when I make a call.
For a SSN use https://www.ssn-verify.com/
Be sure you use the right state for your number and use a number that coincides with the age you are portraying.
For a zipcode use https://www.getzips.com/
You can put in the area code you are calling from and it will give you a list of cities that you can use.
Then got to https://www.realtor.com/ to find a house address. These are homes for sale and you can check if they are empty by how long they have been for sale. This will prevent swatting.
If you are using a burner number, you can look this all up before your call and be prepared with your story.
If you are using a random number generator, you have to be quick to look up the zip and address while you are connecting.
If you use fake name generator, be aware that the SSN they provide are not verified to be real nor are the address correct. Sometimes they do not exist or the zipcode is not right. Scammers are pretty savvy and will look it up, If you use a police address, they know as they do if you use a USP store address. Some are less sophisticated but I have found they do check more often than not.
Hope this helps.
