Depends on who issued it - for an exact date, contact the issuing agency. Red Cross CPR certifications last for 2 years and American Heart Association certifications last for 2 years.

Best case practice yearly in regards to OSHA training requirements (BBP).
If your certification is more than 30 days expired, you are no longer eligible to take a renewal or challenge course, but rather will need to take a full certification course again either in-person or online. I moved to a different state after receiving my CPR certification.
