It is possible, but not reliable.
Most facilities require the inmate ID number on all incoming mail to make sure it is delivered to the correct person. Without it, the mailroom has to rely only on the inmate’s name, which can create confusion.
What can happen:
- The mailroom staff may figure out who it belongs to and deliver it
- Or they may return it to sender for missing required information
- In some cases, it may be held or delayed while they try to verify
Why the ID number matters:
- Many inmates have similar or identical names
- The ID number is the primary way they match mail to the right person
- It speeds up delivery and reduces errors
How often does it still get delivered?
- It really depends on the mailroom staff
- Some will go the extra step to deliver it
- Others will strictly follow policy and send it back
Best practice going forward:
- Always include:
- Full name
- Inmate ID number
- Correct facility and housing info if available
Bottom line:
- There is a chance your letter gets through without the ID
- But there is also a strong chance it will be returned
- Using the ID number is the safest way to ensure delivery
If you are unsure of the ID, it is better to wait and confirm it before sending more mail.
