In this work, the hydrogen's ionization energy was used to constrain the freeparameter $b$ of three Born-Infeld-like electrodynamics namely Born-Infelditself, Logarithmic electrodynamics and Exponential electrodynamics. Ananalytical methodology capable of calculating the hydrogen ground state energylevel correction for a generic nonlinear electrodynamics was developed. Usingthe experimental uncertainty in the ground state energy of the hydrogen atom,the bound $b>5.37\times10^{20}K\frac{V}{m}$, where $K=2$, $4\sqrt{2}/3$ and$\sqrt{\pi}$ for the Born-Infeld, Logarithmic and Exponential electrodynamicsrespectively, was established. In the particular case of Born-Infeldelectrodynamics, the constraint found for $b$ was compared with otherconstraints present in the literature.
