If an applicant chooses to switch to their replacement string during the replacement period, that string permanently and irreversibly replaces their original applied-for string. Under no circumstances can applicants switch back to the originally applied-for string after the replacement period ends.
A replacement string cannot be used:
- If an applicant’s replacement string is identical to another applied-for string.
- If an applicant’s replacement string is identical to another applicant’s replacement string.
Learn more about the replacement period and replacement strings in the Pre-Evaluation Processes FAQS.
