In early January 1906 the Banco de Zacatecas and the branch of the Banco Nacional de México in Zacatecas refused to accept notes of the Banco de Londres y México, especially the larger denominations, not through mistrust but because, according to the Banco de Zacatecas, as there was no agency in Zacatecas it was necessary to send the notes to Aguscalientes to redeem them. However, El Correo de Zacatecas felt that the measures were also due to the scarcity of cash and to the prudence of the banks themselves to preserve as much cash as possibleLa Gaceta de Guadalajara, 7 January 1906.

In October 1888 it was reported that the Banco de Londres, México y Sud América was planning to establish a branch in GuadalajaraEl Cronista, 17 October 1888.
The bank’s branch, on the corner of 16 de Septiembre and Madero was designed by the American Charles Strange. The building was on an almost square lot of about 26 metres per side. It has two floors that occupy the entire lot with a third added later. The main characteristic of the façade is the use of red brick in almost all of it, except for the details of grey quarry in pediments and cornices.
