A federal tax ID number (or TIN/EIN) is a nine-digit number assigned after an organization registers themselves with the IRS. This number will always be nine digits (no letters or special characters) and is typically formatted like so: 12-3456789.

If your organization is registered with the IRS, it will have a federal tax ID number. If you are not able to locate your federal tax ID number, feel free to contact your treasurer, finance person, national office, or anyone in your organization that may have access to this information.

Yes! If your organization falls into one of these categories, it will have a federal tax ID number.

If the number you are using has more or less than nine digits or includes letters, this is not your federal tax ID number and not a number we may use.

When verifying your tax information, the IRS doesn’t tell us what doesn’t match, only that the name and federal tax ID provided aren’t a match in their system. We aren’t informed which piece of the information is incorrect. If you receive this message, it means that either the name in line 1 of the W-9 doesn’t match the federal tax ID, vice-versa, or both are incorrect. Please verify this information with your organization again before resubmitting.

No problem! If you’re okay with the check being made payable to the district and school, we can write a check to your school district without you submitting a federal tax ID number or W-9. In step 3 of the Fundraiser Approval Process, you’ll have the option to have the check made payable to your district and school. Follow the prompts on this page to select your school district and specific school. This will bypass the W-9 and allow us to approve your fundraiser without further tax information. If you need the check written to an organization other than your school district, (like a PTA/PTO or booster club) we’ll need the tax information and possibly a W-9 completed.

If we write the check to a public college or university, we can proceed without a W-9. In step 3 of the Fundraiser Approval Process, you’ll have the option to have the check made payable to your public college or university. Follow the prompts on this page to select your school. This will bypass the W-9 and allow us to approve your fundraiser without further tax information. If you need the check written to an organization other than your school, we’ll need the tax information and possibly a W-9 completed.

You can ask the IRS to search for your EIN by calling the Business & Specialty Tax Line at (800) 829-4933. The hours of operation are 7:00 a.m. – 7:00 p.m. local time, Monday through Friday. An assistor will ask you for identifying information and provide the number to you over the phone, as long as you are a person who is authorized to receive it.

To change your tax information, please email and let us know. We will reset your tax information, but please note that this will take your fundraiser out of “approved” status until we have new tax information submitted and verified. You will have four days to re-complete the tax information; if tax information isn’t supplied within the four day window, the fundraiser will expire and you will lose your date on the calendar.

We’d love to, but the IRS requires we verify fresh tax information for each organization that we partner with.


We are unable to write a check or envelope to anyone’s attention or include a “courtesy of” note, due to the way our checks are processed. Any “ATTN” or “℅” instructions given will not be included on your check/envelope. Feel free to include any directions in the check’s memo line, which you will have the chance to edit during the fundraiser approval process.

Our checks take about 30 days to process and are then sent via U.S. mail. Checks will typically arrive between 30-45 days once your fundraiser is complete.

Absolutely! Once your fundraiser is hosted and complete, you will be sent a required acknowledgement letter to fill out. You can put all of the necessary information in the memo line section of this form.

Our checks expire 180 days after they are issued.

Please mail your check to a valid and reliable address that will be easy for your organization to obtain the check, with consideration for things like specific mailboxes and offices/locations being closed during holidays or summer break.

Our checks are sent directly to you from our accounting department, unfortunately it is not possible to pick up a check from your local Xochimex restaurant.

We are unable to write checks to individuals, only to organizations. We ask for your organization’s federal tax information in order to verify everything and ensure we can write you a check after your fundraiser.

Our checks go through an automated print and envelope stuffing process (to the tune of 1,500/day), so we won’t be able to handwrite or include any extra information on your check/envelope. If you are forwarding your check to another organization and need to include specific information, consider adding it in the memo line field or having the check mailed to your local address before sending it on to its final destination.


All promotion must be done ahead of time and not in our restaurant or on the premises to our regular customers. Violating this policy may result in your fundraiser being cancelled.

We are thrilled to support your organization with our fundraiser, but we won’t be able to accommodate tables, donation jars, decorations, or distribution of information. We need to do everything in our power to be the very best neighbors to our surrounding businesses, and also ensure that we are making those guests who are not dining with us in conjunction with your fundraiser feel at home and unsolicited.

In order for your purchase to count towards your fundraiser, your supporters must either a) verbally tell our cashier of their participation, b) show a physical fundraiser flyer, c) show a digital flyer on a smartphone or other mobile device.

Online or in-app orders cannot be counted towards fundraisers. This is communicated on partner emails as well as fundraiser flyers to avoid confusion for our partners and their supporters. The only way that orders will be counted towards the fundraiser is if they are ordered and paid for in-store during fundraiser hours.

We give back 25% of the proceeds brought in by your event, regardless of how much it produces.

Nope! No matter what amount of money your event brings in, you will receive 25% of the proceeds.

We don’t need staff or team members to be there during the fundraiser to facilitate, however, keep in mind that you do need your supporters to show up and tell our cashiers that they’re there supporting the fundraiser (which is how your group raises funds for the event). The more money spent by your supporters, the more you receive back!

No problem, email us at and we will help you set up a new date and time. Note: you will only have one opportunity to reschedule, so please be sure to consider the new date carefully before rescheduling.

To update your flyers, just email and we’ll get those updated for you within two business days.


Our fundraisers are extremely popular, and we want to accommodate as many different groups as possible. As a result, we limit each organization to one fundraiser every six months. If you are interested in fundraising with us again in the future, feel free to reach out again in six months by visiting to apply.

Due to the popularity of our fundraisers, we must limit the number of participating restaurants to one. To maximize your results, please choose the restaurant that is most centrally-located for your supporters.

We only host fundraisers during our slower evening hours. When we host them during our peak lunch hours, it tends to cause long lines and a really negative experience for both your supporters and our regular guests. We stick to the two time-frames of 4-8pm and 5-9pm.

Please do not make any edits to our fundraiser flyers. These are created by our Design team and must stay within our branding requirements. We are unable to add your organization’s logo to our flyers.

Yes! But, you’ll have to follow this simple process: Call your nearest Xochimex location to place your order (at least 24 hours in advance) to be picked up during the timeframe of your fundraiser and let them know that you want to pay upon pickup. When you pick up your order, alert the cashier before payment that you would like it to count towards your fundraiser. And just like that, 25% goes back to your group!
