Are copper IUDs an effective form of birth control?

Yes! Copper IUDs are more than 99% effective.

Although no form of birth control is 100% effective (other than abstinence), there is an extremely small chance of pregnancy while using a copper IUD.

While no method of birth control is perfect, copper IUDs are a highly effective form of birth control. The World Health Organization cites a failure rate, the number of couples who get pregnant in the first year of use of copper IUDs as about 7 in 1000 couples. Compare this to the rate of 80 pregnancies in 1000 couples in the typical use for birth control pill users.
The copper IUD available in the United States is the T380A, or Paragard. It has been available since 1988. Tens of millions of women around the world use this method, more women than use the birth control pill.
