Executive summary

A patchwork of community-run rapid‑response hotlines exists around the country, but authoritative, county‑level contact details for the five most populous U.S. counties are uneven in the reporting provided: clear, citable hotline numbers and hours are available for Harris County (Houston) and San Diego County from the sources reviewed, while no verified rapid‑response phone number or published hours for Los Angeles, Cook (Chicago), or Maricopa (Phoenix) counties appear in the supplied documents [1] [2]. Where local rapid‑response lines are not documented in the provided reporting, federally run ICE hotlines and national detention hotlines provide 24/7 or specified coverage and are cited below as alternatives [3] [4] [5].

1. Harris County (Houston): a documented local rapid‑response hotline

Community reporting and compilations list a Houston ICE raids and checkpoints hotline as 713‑862‑8222, presented explicitly as a local rapid‑response contact for the Houston area (Harris County) in a nationwide collection of rapid‑response hotlines [1]; the document does not provide standardized published hours for that local line beyond implying emergency/after‑hours use in the context of raid reporting [1].

2. San Diego County: a named rapid‑response number with local network linkage

San Diego’s Rapid Response Network hotline appears in the directory of immigration hotlines as 1‑619‑536‑0823; the listing identifies it as the San Diego Rapid Response Network hotline but the source does not state a formal hours schedule, leaving responders’ availability described only by the network’s role as an emergency contact [2].

3. Los Angeles County: local networks named but no verifiable phone or hours in supplied sources

Los Angeles County is repeatedly referenced as covered by the Immigrant Defenders Law Center Rapid Response Legal Resource Hotline and other Southern California rapid‑response coalitions in the community resource material, but the supplied CCIJustice and related excerpts do not include a direct, citable phone number or hours for Los Angeles County specifically in the documents provided [6] [1]; therefore the precise LA county hotline number and operating hours cannot be confirmed from these sources.

4. Cook County (Chicago) and Maricopa County (Phoenix): absence of county hotline data in the available reporting

The collected material includes many local and regional hotlines for California, Texas and northeastern states but does not contain a verified rapid‑response hotline number or published hours for Cook County (Chicago) or Maricopa County (Phoenix) within the supplied snippets, so any claim about specific phone numbers or schedules for those counties would exceed what the available reporting supports [2] [1].

5. Federal and national alternatives: ICE tip lines and the National Immigration Detention Hotline

For callers seeking a 24/7 federal point of contact, ICE’s public contact points include an ERO/tip line and toll‑free numbers: ICE’s public contact listing gives a U.S./Canada number (866‑347‑2423) reported as available 24 hours a day, seven days a week [7], and ICE’s Tip Line is described as accepting tips 24/7 (listed as 866‑DHS‑2‑ICE in ICE materials) with after‑hours capacity for time‑sensitive enforcement calls [3]. For people inside detention, Freedom for Immigrants operates the National Immigration Detention Hotline reachable by dialing 9233# from a facility phone (with volunteer staffing described and limited published hours in some materials—FFI’s national hotline is noted in reporting as operating Monday–Friday 12pm–8pm PST in one compilation while the organization aims to expand coverage) [5] [1]. ICE also announced a toll‑free hotline for individuals who believe they may be U.S. citizens or crime victims in custody at 855‑448‑6903, staffed 24/7 by ICE personnel at the Law Enforcement Support Center according to a DHS/ICE bulletin [4].

Conclusion and reporting limits: the provided documents verify local rapid‑response hotlines for Houston (713‑862‑8222) and San Diego (1‑619‑536‑0823) and federal 24/7 contacts (866‑347‑2423; 866‑DHS‑2‑ICE; 855‑448‑6903) plus the detention line access code 9233#; however, definitive, citable phone numbers and published operating hours for Los Angeles County, Cook County, and Maricopa County rapid‑response hotlines do not appear in the supplied sources, and readers should consult local immigrant‑rights coalitions, county government pages, or the community rapid‑response networks named in the reporting (e.g., Immigrant Defenders Law Center, CCIJustice) for current, locally maintained contact details [6] [8] [1].
