As filed, from the IRS e-Postcard file of 19 October 2026. The IRS publishes only each organization's most recent postcard, so earlier years are not shown. A 990-N carries no financial detail. The postcard also gives the principal officer's address, which is not shown here.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

Grants received

The 10 largest by cash amount. The API serves every itemized grant.

Related organizations

From Schedule R Part II, where a filer lists the tax-exempt organizations it is related to by control. It does not record shared board members or money.

Declared as related by

California fundraising campaigns

Campaigns run by paid fundraisers, commercial coventurers and thrift stores naming this organization, as California published them. Both figures are as filed, and what the first one counts depends on the campaign type — a coventurer or a thrift store files its own sales rather than money collected for the charity. The 990 reports this only as a yearly total, never per campaign.

  • ZARA USA INC.

    $11,628 in sales

    2022 Commercial Coventurer

    $11,628 to charity

  • ZARA USA INC.

    $65,787 in sales

    2021 Commercial Coventurer

    $65,787 to charity

Amounts are as filed and do not add up: a commercial coventurer reports one promotion's whole gross once for each charity that shared in it. A campaign may also name more than one registered charity, in which case it appears on each.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Not present in the most recent drop.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.

What this page reflects

The registration facts above come from the IRS Business Master File published 13 October 2026 and read 23 October 2026, for every organization at once. No return for this organization has been parsed, so nothing above comes from a filing.
