We are not aware of any Illinois or federal laws that would prohibit a national bank from establishing a mobile ATM (or a state bank, for that matter). The IDFPR has stated in an Interpretive Letter that mobile ATMs are permitted under Illinois law (Interpretive Letter 93-32 (December 22, 1993)). In addition, a mobile ATM is not subject to any OCC notice or application requirements — under the OCC regulations, a mobile ATM “is not a ‘branch’ . . . and is not subject to state geographic or operational restrictions or licensing laws.” 12 CFR 7.4003.
