Requesting a check from Upromise
From the Upromise Account FAQ:
You can withdraw your Upromise contributions at any time during your membership. To withdraw company contributions from your Upromise account, submit a letter in writing to Upromise requesting a withdrawal from your Upromise account. The letter must state your full name and exact amount that you would like to withdraw, up to total amount available in your account, pending contributions are not eligible for withdrawal.
For the protection of our members, we require that your letter either be notarized or contain a Signature Guarantee if the withdrawal request is in excess of $200. A Signature Guarantee is a guarantee you can obtain from a financial institution, such as your bank, that your signature is yours and that it is genuine.
Withdrawal letters should be sent to:
ATTN: Customer Care
P.O. Box 55555
Boston, MA 02205-5555
Checks are sent once per calendar quarter, so you should typically receive your check within 12 weeks of your request being received.
I make my Upromise withdrawal requests with a letter similar to the one below:
