Will adding my spouse as an authorized user on my credit cards raise our FICO credit score?

What I want to know is whether adding my spouse to my credit cards and her adding me to her credit cards increase our FICO scores? We both never missed a payment and were always on time to all of our credit cards. Thank you for your help.

1. It actually may lower it. The more available unsecured limit for spending, the lower your score.
2. please do not do this. If you both never miss payments you can increase your score by making sure that your bill to debt ratio is not higher than 30 percent. Protect each of your scores in case one of you looses a job etc one of you can sacrafice if needed and take a hit if they are seperate then the other can finance car etc. I dont think that adding each other will help at all and might hurt
3. An authorized user will not affect it at all. If Your spouse has good credit, then you want to re-apply as joint owners. If your spouse has worse credit than you, don't do it.
4. If you add each other as joint on the accounts, the accounts will be reported on both credit reports and used to calculate your score. Authorized users not longer get the benefit of the good credit. The rules changed and the account wouldn't be counted in the score.
