There are many instances in which you might want to change your age with a fake birth certificate. In many cases you will only be able to change your age on your birth certificate and not on your other identification. This is due to the fact that a fake birth certificate may not look like the birth certificates for your state. However, if you were born out of state you may be able to fake your birth certificate and get a new identification card with the “corrected” age on it.
The most common reason to want to change your age on your birth certificate is so that you can be younger. This is especially true of women who want to date younger men. They can make themselves younger on their identification and that way convince younger men to date them.
Another common reason to want to change your age is to be older. You may want to be old enough to buy alcohol, gamble, or stay out after curfew. Using a fake birth certificate for these purposes is dangerous, however, because you are more likely to get caught by authorities. However, again, if you have an out of state birth certificate you may be able to get away with getting an official identification card with the certificate, especially if you have never had an identification card in that state before.
Keep in mind that whether you make yourself older or younger, your fake birth certificate needs to be believable. That means that you should look the age you put on your fake certificate. If you look fifty, do not try to say that you are thirty. If you look twelve but are eighteen, don’t try to say you are twenty one. It must be believable if you are not going to get caught.
