The Complete Guide to Sending Mail to an Inmate at McHenry County Jail

Address the envelope with the inmate's full name and their Jail ID number. Below that, use the facility's mailing address exactly as shown: McHenry County Jail, 2200 N. Seminary Avenue, Woodstock, IL 60098. If the name or ID is missing or hard to read, your mail can be delayed or flagged as unauthorized.

All mail for inmates at McHenry County Jail must come through the U.S. Postal Service. You cannot drop off letters or other mail items at the jail in person.

Once the jail receives incoming mail from the Post Office, it gets delivered to inmates within 24 hours, as long as it's not a weekend or holiday and there are no pressing circumstances. If you're mailing something close to a weekend or holiday, build in extra time.

Required Details

• ✓ Inmate’s full name
• ✓ Inmate ID number
• ✓ Sender name
• ✓ Sender return address

Always include your name and return address. Mail that arrives without this information is considered unauthorized. Instead of being delivered, it gets placed in the inmate's property and won't be returned to them until their release.

If the jail finds unauthorized items in your mail, the entire letter and everything inside it gets sent back to you. Even a single problem item means the whole mailing comes back.

1. Watch for an unauthorized-item situation - if something cannot be accepted through the mail, it may need to be handled outside normal delivery.
2. Pick the item up at the facility if needed - unauthorized items can be picked up at the McHenry County Correctional Facility.
3. Go during pickup hours - Monday through Friday, 8 a.m. to 4 p.m., excluding holidays.
